Evers made his MLB debut with the Cubs on September 1 at shortstop, as Selee moved Joe Tinker from shortstop to third base.[1] Only three players in the National League (NL) were younger than Evers: Jim St. Vrain, Jimmy Sebring, and Lave Winham.[6] Three days later, Selee returned Tinker to shortstop and assigned Evers to second base.[1] In his month-long tryout with the Cubs, Evers batted .222 without recording an extra-base hit and played inconsistent defense.[1] However, Lowe's injury did not properly heal by spring training in 1903, allowing Evers to win the starting job for the 1903 season.[1] Lowe recovered during the 1903 season, but Evers' strong play made Lowe expendable; Evers finished third in the NL in fielding percentage among second basemen (.937), and finished fifth in assists (245) and putouts (306).[7] The Cubs sold Lowe to the Pittsburgh Pirates after the season.[8] Evers played 152 games in the 1904 season.[1] Defensively, his 518 assists and 381 putouts led the NL, though his 54 errors led all NL second basemen.[9]

During the 1906 season, Evers finished fifth in the NL with 49 stolen bases,[10] and led the league with 344 putouts and led all second basemen with 44 errors.[11] The Cubs won the NL pennant in 1906, but lost the 1906 World Series to the Chicago White Sox four games to two; Evers batted 3-for-20 (.150) in the series.[12] During the 1907 season, Evers led the NL with 500 assists.[13] The Cubs repeated as NL champions in 1907, and won the 1907 World Series over the Detroit Tigers, four games to none, as Evers batted 7-for-20 (.350).[14]

Evers with the Cubs, circa 1910

During the 1908 pennant race, Evers alerted the umpires to Fred Merkle's baserunning error in a game against the New York Giants, which became known as "Merkle's Boner". Al Bridwell hit what appeared to be the game-winning single for the Giants, while Merkle, the baserunner on first base, went to the clubhouse without touching second base. Evers called for the ball, and the umpire ruled Merkle out.[1] NL presidentHarry Pulliam ruled the game a tie, with a makeup to be played. The Cubs won the makeup game, thereby winning the pennant.[1][5][8] The Cubs then won the 1908 World Series over Detroit, four games to one, as Evers again batted 7-for-20 (.350).[15] For the 1908 season, Evers had a .300 batting average, good for fifth in the NL, and a .402 on-base percentage, second only to Honus Wagner.[16]

Evers drew 108 walks during the 1910 season, trailing only Miller Huggins.[17] However, Evers missed the end of the season with a broken leg.[18] Without Evers, the Cubs won the NL pennant, but lost the 1910 World Series to the Philadelphia Athletics, four games to one.[19] Evers agreed to manage the Navy Midshipmen, a college baseball team, in 1911, despite the opposition of Cubs' manager Frank Chance.[20] He experienced a nervous breakdown in 1911; returning to the Cubs later in the season, he played in only 46 games that year.[1][21] Evers indicated that this was a result of a business deal that cost Evers most of his savings.[1] Evers rebounded to bat .341 in 1912, good for fourth in the NL,[22] and he led the NL with a .431 on-base percentage.[1] Team owner Charles W. Murphy named Evers manager in 1913, signing him to a five-year contract, succeeding Chance.[1]

After the 1913 season, Evers was offered $100,000 ($2,535,017 in current dollar terms) to jump to the Federal League, but he opted to take less money to remain with the Cubs.[23] In February 1914, after Evers signed his players to contracts, Murphy fired Evers as manager and traded him to the Boston Braves for Bill Sweeney and Hub Perdue.[23] Murphy insisted that Evers had resigned as manager, which Evers denied. Evers insisted he was a free agent,[24] but the league assigned him to the Braves.[23] He signed a four-year contract at $10,000 per season ($250,133 in current dollar terms), with a $20,000 signing bonus.[25]

During the 1914 season, the Braves fell into last place of the eight-team NL by July 4. However, the Braves came back from last place in the last ten weeks of the season to win the NL pennant.[4] Evers' .976 fielding percentage led all NL second basemen.[26] The Braves defeated the Philadelphia Athletics in the 1914 World Series, four games to none,[27] as Evers batted 7-for-16 (.438).[28] Evers won the Chalmers Award, the forerunner of the modern-day Most Valuable Player award, ahead of teammate Rabbit Maranville.[1][29]

Evers was limited in 1915 by injuries, and also served suspension for arguing with umpires.[1] After a poor season in 1916, Evers began the 1917 season with a .193 batting average.[1] Due to Evers' declining performance, the Braves placed Evers on waivers at mid-season, and he was claimed by the Philadelphia Phillies.[1] Evers rejected an offer to become manager of the Jersey City Skeeters of the International League that offseason.[30] He signed with the Boston Red Sox as a player-coach for the 1918 season,[31] but was released without playing a game for them.[30] Not receiving another offer from an MLB team, Evers traveled to Paris as a member of the Knights of Columbus to promote baseball in France.[32]

Evers joined the New York Giants during the 1920 season, serving as a coach.[33] He managed the Cubs again in 1921, succeeding Fred Mitchell. With the team struggling, Evers was fired in August and replaced with Bill Killefer.[34] The Cubs finished seventh out of eight in the NL that season.[4]

Evers served as a coach for the Chicago White Sox in 1922 and 1923.[4] He returned to second base in 1922, filling in for an injured Eddie Collins. Evers played in one game for the White Sox as Collins recovered.[35]

Evers was named the White Sox acting manager for the 1924 season, succeeding Chance, who was ordered home due to poor health.[3] However, Evers suffered from appendicitis during the season, missing time during the year,[5] and the White Sox opened up a managerial search when Chance died in September.[36] The White Sox replaced Evers with Collins after the season.[37]

Evers rejoined the Braves as a scout.[4] As Braves owner Emil Fuchs sold manager Rogers Hornsby to the Cubs and assumed managerial duties himself for the 1929 season, Fuchs hired Evers as a coach. Fuchs had no experience as a field manager,[38] and so Evers became captain of the Braves, directing the team during the game and dealing with umpires.[39] Evers and fellow coach Hank Gowdy played in one game in the 1929 season, coming into the bottom of the ninth inning on October 6, 1929.[40] In the process, Evers became the oldest player in the league for the year.[41]

Though Evers and Tinker were part of one of the most successful double-play combinations in baseball history, the two despised each other off of the field.[1] They went several years without speaking to each other after one argument.[50] When Chance once named Tinker the smartest ballplayer he knew, Evers took it as a personal affront.[51]

Evers operated a sporting goods store in Albany, New York in 1923. However, Evers lost his money and filed for bankruptcy in 1936.[52][53] The store was passed down to Evers' descendants.[54] He also worked as superintendent of Bleecker Stadium in Albany[55][56] and spent time teaching baseball to sandlot players.[57]

Evers retired in 1918, having batted .300 or higher twice in his career, stolen 324 bases and scored 919 runs. He frequently argued with umpires and received numerous suspensions during his career.[62] His combative play and fights with umpires earned him the nickname "The Human Crab".[55]

The Merkle play remains one of the most famous in baseball history. The ball used in the Merkle play was sold at an auction in the 1990s for $27,500, making it one of the four most valuable baseballs based on purchase price.[65] Evers' role in Merkle's boner cemented his legacy as a smart ballplayer.
